Jim McIntyre says goalkeeper Dorus De Vries must not shoulder the blame for consigning Dunfermline to relegation after his blunder against Inverness.
Dorus De Vries made an expensive mistake against Inverness
"Dorus De Vries has saved us so many times during this run," said the Pars striker after the 2-1 defeat.
"We can attach absolutely no blame to him because he has been out of this world this season.
"I am sure he will go and play for a top, top club one day because he is that good."
McIntyre had given Dunfermline the lead in a game they needed to win to give them a chance of avoiding relegation on the final day this coming weekend.
But De Vries' slip and a cruel deflection gave Inverness victory, while St Mirren came back from two goals down to defeat Motherwell to send the Pars to Division One.
We are relegated because we were the poorest team over the course of the season

"The manner that the second goal went in, you sometimes think these things are not for you," McIntyre told Dunfermline's website.
"You have got to give a lot of credit to St Mirren.
"They have come back from two goals down to win 3-2, so congratulations to them.
"If we had won on Saturday, we would have taken it to the last game, but we never.
"At the end of the day, the table doesn't lie.
"We are relegated because we were the poorest team over the course of the season.
"We have to take it on the chin.
"It is going to be a hard week trying to get over it because we have a Scottish Cup final to look forward to.
"It will be a difficult summer, but we have a massive game against Celtic, although right now that feels a million miles away."
